Macroevolutionary dynamics of ecosystem‐engineering and niche construction.

That the activities of organisms influence their surrounding ecological communities, and the environment, has long been appreciated by palaeontologists, as has the role of these activities on both ecological and evolutionary processes. Spillover effects extend the range of ecosystem‐engineering through ecological networks, generating network effects that because of their non‐trophic nature can be challenging to track. Moreover, the cumulative effect of organismal activities can persist far beyond the lifespan of individual organisms, producing ecological inheritances that influence macroecological and macroevolutionary dynamics. This contribution surveys macroevolutionary patterns arising from ecosystem engineering, their potential contribution to evolutionary radiations, and the significance of ecosystem engineering as a public good in the success of evolutionary innovations. Anecdotally, such activities appear to have made important contributions, but considerable work is required for more rigorous understanding. I describe two challenges: the need for palaeontologists to collect abundance data in a way that facilitates comparative study, and the importance of more robust models of ecological (not just trophic) networks involving multigraphs and hypergraphs.
